Whilst all the feedback about XDMS is very interesting, I was listening to the best music I have ever heard by a long way in my house last night using Roon and would be perfectly happy to call it a day right now. I find it hard to imagine where/how things could be improved but will certainly be happy if XDMS proves me wrong.
In the early part of this year, I tried out a number of different items of equipment with the aim of finally hitting an endpoint with my main system. I am not in the same equipment testing league as
@romaz, but it was quite a challenge and took some considerable amount of time and effort. Every single item was re-assessed and compared with the exception of my speakers and headphones. When I reached what I considered to be my optimal setup, I then reconstructed my original system and the difference was staggering. After what I had got used to, it was actually hard to listen to my old setup which was sounding thin and hard by comparison. I then decided to rebuild what I had considered as the optimal combination piece by piece in order to try and quantify how much each item was contributing to the whole and, what was really quite surprising, was to discover that the Extreme accounted for by far the largest portion of the improvement. I had four DAC’s at one point and whilst the differences between them could be heard, the differences and degree of uplift achieved was not as significant as that contributed by Extreme. This might seem a bit of an extreme comment, but I consider the improvement lent by adding the Extreme to be about on par with that achieved by my adding a new DAC, preamp and power amp together. Hard to believe and certainly not what I was expecting, but it did make the cost of adding the Extreme to be far easier to accept.
